Social media video maker FAQs
How does the social media video maker work?
You describe the video you want in Syren, Synthesia’s AI video agent, and it writes and renders it live. Your prompt sets the audience, tone, visual style, narration, and music, and Syren handles the motion, type, and pacing. Then you steer it by chat or by editing elements directly.
Is the social media video maker free?
Yes, you can try the social media video maker for free. A two-minute video with up to two rounds of edits typically uses 1,000 to 2,000 credits. Videos on the Basic plan carry a watermark and can be downloaded and shared, while Starter and Pro videos have no watermark.
Can I create social media videos with AI from my own content?
Yes. Add documents, images, videos, PowerPoint files, or YouTube links with the + button, or start from an idea in the prompt. Syren can ask follow-up questions, such as who the video is for, and offers answer options.
Which video shapes does the social media video maker support?
Syren makes tall 9:16 and wide 16:9 videos, up to three minutes long. Tall suits mobile and social feeds, and wide suits websites and presentations. You choose before you send your first prompt, and you can’t choose when you start from an example video.
Can I post my videos straight to social media?
No, Syren doesn’t post to social media. Select Generate, choose a resolution up to 1080p, download your video, and upload it to each channel yourself.
Can I add my logo and brand to my videos?
Yes. Syren applies a baseline brand using your own colors, and you can add your logo and other brand assets when you start in Syren. To use your own Personal Avatar or cloned voice, create your video in Synthesia Studio.
Can I use Syren videos commercially, and who owns them?
Yes. You can use Syren videos for marketing, product launches, and ads, and you own the videos you create, the same as any video made in Synthesia. Make sure you have the rights to anything you upload, such as images, footage, or other companies’ logos.
Can I edit a social video after Syren makes it?
Yes. Ask Syren in chat to change the script, swap the voice, restyle a scene, or fix the music, shot types, or pronunciation. You can also select a heading, image, or shape on the picture to move it or retype it, and those edits apply at once.
When should I use Syren instead of Synthesia Studio?
Use Syren when you want a creative, designed video fast, like a launch reel, an explainer, or a short announcement. Use Studio when every script line and scene has to be exact and repeatable, or when you need to update and translate a video at scale, as with training, compliance, and onboarding content.
Not just a social media video maker
Synthesia is an end-to-end AI video platform for creating, localizing, and managing video at scale. Syren builds social videos from a prompt, the AI video generator turns docs into video in Studio, and Avatars put a presenter on screen without a shoot.
Then translate every video for new markets, start from templates in the marketing video maker, and refine it all in the AI video editor. One platform, from the first idea to every market.
